Sometimes mails are delivered to wrong account
the following problem exists since first's Zimbra 6 release, also with release 6.0.6:
Very sporadically, emails for recipient xy are not delivered to xy's mailbox, but to my personal one. Today, this also happened with intermal Zimbra emails - the daily status reports shall be sent to admin@..., but were delivered to my user account.
Does anyone have an idea why this sometimes happens? Usually I would say "That a definite no-go", but maybe there is an easy fix for this?
